Kua tāruatia ki te papatopenga
3\left(x-1\right)-18x=-25
Me whakarea ngā taha e rua o te whārite ki te 18, arā, te tauraro pātahi he tino iti rawa te kitea o 6,18.
3x-3-18x=-25
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te x-1.
-15x-3=-25
Pahekotia te 3x me -18x, ka -15x.
-15x=-25+3
Me tāpiri te 3 ki ngā taha e rua.
-15x=-22
Tāpirihia te -25 ki te 3, ka -22.
x=\frac{-22}{-15}
Whakawehea ngā taha e rua ki te -15.
x=\frac{22}{15}
Ka taea te hautanga \frac{-22}{-15} te whakamāmā ki te \frac{22}{15} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
